赝火花放电是最近几年才被人们注意并开始深入研究的低气压气体放电现象.利用这一现象作成的多极板放电室(图1),充以10~(-2)—10~(-1)乇气压的某种气体(如H_2、H_e N_2、空气、Ar等),当放电室两端电压达一定值(几十至—百千伏)时就能得到重复频率随气压和外加电压变化的毫微秒(1—100毫微秒)的强流电子束和离子 Pseudospark discharge is a low-pressure gas discharge phenomenon which has been noticed and started to be researched in recent years.Using this phenomenon, a multi-polar plate discharge chamber (Figure 1) is filled with 10 -2 (-10 ~ -1) Torr pressure of a gas (such as H_2, H_e N_2, air, Ar, etc.), when the voltage across the discharge chamber reaches a certain value (tens to hundreds of kilovolts) will be able to get repetition frequency with pressure and applied Voltage changes in nanoseconds (1-100 nanoseconds) of intense current beams and ions
